FIELD

This disclosure relates generally to sleep aids, more particularly to time release sleep aids.

BACKGROUND

Sleep disorders such as insomnia or alterations in the sleep-wake cycle are common in human beings. It has been shown in a Gallup poll survey that 95% of the adult population had experienced insomnia (Rosekind, M., J. Clin. Psychiatry, 1992, 53:4-6). The current literature maintains consistently that approximately one third of all people have sleep problems in any given year.

Sleep disorders can have serious consequences by themselves and can lead to numerous other medical problems. As a result, numerous remedies and methods have been created to deal with sleep disorders. See Treisman et al., “Insomnia,” Johns Hopkins POC-IT Center, 2010 pp. 1-3. Some examples of sleep medications include over-the-counter medicines such as TYLENOL PM™, compositions containing melatonin, herbal remedies, as well as pharmaceuticals such as zolpidem, quetiapine, and many others. While some of these sleep medications may be effective, tolerance generally develops for most medications requiring increasingly higher dosages. Other sleep medications either do not work well, have serious side effects, or both. For example, some medications do not continue to work over extended periods and the patient wakes up during the night.

There is a significant need for a sleep composition and method that is safe and effective. There is also a need for asleep composition that is effective over an extended period, and does not have significant side effects. The compositions and methods disclosed herein address these and other needs.

DETAILED DESCRIPTION

Compositions that provide a modified release profile of active agents are disclosed herein. The active agents can include one or more sleep promoting active agents, one or more sleep quality active agents, and/or one or more sleep recovery active agents, and optionally one or more next day active agent. The one or more sleep quality active agents, one or more sleep recovery active agents, and/or one or more next day active agents can be combined with a binder, which can include a polymeric binding agent.

“Modified release” as used herein refers to a change in the availability or release profile of an active agent or a portion thereof from its dosage form compared to the availability or release profile of the active agent in its conventional unmodified form.

“Modified release” can be evidenced by modified dissolution characteristics of the active agent in its dosage form compared to the active agent alone. Modified release can encompass sustained release, controlled release, timed release, burst release, prolonged release, delayed release, immediate release, slow release, extended release, or combinations thereof. As is also known in the art, suitable mechanisms for achieving modified release of an active agent include diffusion, erosion, surface area control via geometry and/or impermeable barriers, semi-permeable barriers and other known mechanisms known. In some examples, the disclosed composition can provide an immediate burst release, delayed burst release, and/or delayed sustained release of the active agents in the composition. Methods of making and using the compositions disclosed herein are also provided.

Before the present compositions and/or methods are described, it is to be understood that this disclosure is not limited to specific active agents, such as specific sleep promoting active agents or particular sleep recovery active agents, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting.

As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a polymeric binder” includes mixtures of polymeric binders, reference to “an active agent” includes mixtures of active agents, reference to “the sleep promoting active agent” includes mixtures of two or more such sleep promoting active agents, and the like

Ranges can be expressed herein as from “about” one particular value, and/or to ‘about’ another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as “about” that particular value in addition to the value itself. For example, if the value “10” is disclosed, then “about 10” is also disclosed.

By “treat” or other forms of the word, such as “treated”, “treating”, or “treatment,” is meant to administer a composition or to perform a method in order to reduce or prevent a particular characteristic or event (e.g., sleep disorder). The term “control” is used synonymously with the term “treat.” To treat a sleep disorder, according to the methods described herein, the treatment does not necessarily provide therapy for the underlying pathology that is causing the sleep disorder sensation. Treatment of a sleep disorder can be purely symptomatic. For example, treatment of a sleep disorder can include modifying or improving the sleep-wake cycle of a subject.

The term “active agent” is used interchangeably with the terms “ingredient,” “active ingredient,” “substance,” or “compound,” and refers to a pharmacological agent that can act locally or systemically in the body. The term “active agent” includes agents that can be administered to a subject for the treatment or prevention of a disorder.

It is understood that throughout this specification the identifiers “first” and “second” are used solely to aid in distinguishing the various active agents, features, and steps of the disclosed subject matter. The identifiers “first” and “second” are not intended to imply any particular order, amount, preference, or importance to the active agents or steps modified by these terms.

Binder

The compositions described herein can include a binder. The binder can be biocompatible. “Biocompatible” or “biologically compatible”, as used herein, generally refer to binding agents that are, along with any metabolites or degradation products thereof, generally non-toxic to cells and tissues, and which do not cause any significant adverse effects to cells and tissues when cells and tissues are incubated (e.g., cultured) in their presence. In some examples, the biocompatible binding agent can be generally recognized as safe (GRAS) compliant. GRAS status is an American Food and Drug Administration (FDA) designation that a chemical or active agent added to food is considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements.

In some aspects of the present disclosure, the binder can be a polymeric binding agent. Examples of suitable polymeric binding agents include, but are not limited to, methyl cellulose, ethyl cellulose, microcrystalline cellulose, croscarmellose sodium, dicalcium phosphate, cellulose, hypromellose, hydroxypropyl methylcellulose, carboxymethylcellulose, alkali metal carboxymethyl cellulose, carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, or combinations thereof. Other exemplary binders can include xanthan gum, viscarin, gelatin, starch, glucose, sucrose, polyvinyl pyrollidone, polyvinyl alcohol, gum tragacanth, gum karava, sodium alginate, Laponite CP or SP, or magnesium aluminum silicate gel. The binder can also be coloring agents, taste masking agents, or combinations thereof. In some examples, cellulose-based binders are used.

Any suitable amount of the binder can be used in the compositions herein. For example, the amount of binder can be from about 0.5 wt % to about 99.9 wt % of the composition. For example, the amount of binder can be from about 1 wt % to about 99 wt %, from about 1 wt % to about 98 wt %, from about 1 wt % to about 95 wt %, from about 5 wt % to about 95 wt %, from about 10 wt % to about 95 wt %, from about 20 wt % to about 95 wt %, from about 30 wt % to about 95 wt %, about 40 wt % to about 95 wt %, or about 30 wt % to about 90 wt % of the composition. The amount and/or type of binder included in the composition may be adjusted in order to alter the release profile of the active agents. For example, the amount and/or type of polymeric binding agent encapsulating the active agent may be adjusted to exhibit a sustained release or delayed release profile of the active agent “Encapsulation” as used herein, refers to an agent, for example an active agent, residing primarily within a binder system as opposed to merely residing upon or attaching to the surface of the binder system. In some embodiments, encapsulation of the active agent refers to the active agent dispersed or encased within the binder.

Comestible Matrix

The composition comprising the active agents and the binder can be dispersed in a comestible matrix. The comestible matrix can be a solid, a semi-solid, or a liquid. For example, the comestible matrix can be a powder, a solution, a suspension, or an emulsion. The comestible matrix can be in a form suitable for oral administration, such as a tablet, a capsule, a powder, a granule, or a drinkable preparation. For example, the comestible matrix can include chocolate, marshmallow, hard candy, soft candy, soft chew, taffy, sugarless candies, desserts such as jelly and pudding, confectionery such as cakes, cookies, chewing gum, bubble gum, granola bars, gel beads, gelatin candies, pectin candies, gummies, powdered confectionary for example a stick pack powder, starch candies, lozenges, frozen confectionery such as ice creams, sherbets, and ice-lolly, a beverage, crackers, biscuits, cookies, cakes, breads, capsules, pills, or tablets. In some examples, the comestible matrix is a chocolate matrix. In some examples, the comestible matrix can also be a chew. In other examples, the comestible matrix is a powder that can be added to a beverage such as flavored water, a shot beverage, a multi-dose beverage, tea, concentrated fruit juice, straight juice, carbonated drink, soft drink, or milk beverage. In further examples, the composition can be in the form of a tablet or capsule that can be administered with a beverage such as water, juice, or a dink. The tablet or capsule can be formulated as a chewable formulation.

Modified Release Compositions

When administered to a subject, the disclosed compositions can release certain active agents at certain periods, rather than all at once. For example, the disclosed compositions can (i) release the sleep promoting active agent immediately or within about 30 minutes of administration (immediate burst release) or over a period of about 3 hours beginning immediately or within 30 minutes of administration (immediate sustained release) (ii) release the sleep quality active agent over a period of about 6 hours of administration (sustained or burst release), and/or (iii) release the sleep recovery active agent and/or the optional next day active agent after about 3 hours or more of administration (delayed burst or delayed sustained).

The sleep promoting active agent for immediate burst release can include a composition comprising the sleep promoting active agent and optionally a binder. In some examples, the optional binder includes a material to alter the appearance, taste, smell, or shelf life of the sleep promoting active agent. The sleep promoting active agent can be encapsulated in the optional binder.

The sleep quality active agent can be in the form of a composition comprising the sleep quality active agent and a polymeric binder. The sleep quality active agent and the polymeric binder can be prepared for sustained release, delayed sustained release, or delayed burst release. The sleep quality active agent can be homogenously mixed or encapsulated within (coated) with the polymeric binder. For example, the sleep quality active agent for sustained release can include a composition comprising the sleep quality active agent and a sustained release polymeric binder homogenously mixed. In some examples, the sleep quality active agent for delayed sustained release can include the sustained release active agent (i.e., the sleep quality active agent and the sustained release polymeric binder) coated with a delayed release polymeric binder. In specific examples, the sustained release polymeric binder and/or the delayed release polymeric binder can include a polymer selected from polyacrylate, methylcellulose. CARBOWAX™, or combinations thereof. In some aspects, the release of the active agent can be controlled through a thicker coating layer, pH, osmotic control, or combinations thereof.

The sleep quality active agent can be in an amount of from about 0.5 wt % to about 55 wt %, based on the combined weight of the sleep quality active agent and the polymeric binder. The polymeric binder can be in an amount of from about 0.5 wt,% to about 99.9 wt %, such as from about 50 wt % to about 99.8 wt %, based on the combined weight of the sleep quality active agent and the polymeric binder.

The sleep recovery active agent can be in the form of a composition comprising the sleep recovery active agent and a polymeric binder. The sleep recovery active agent and the polymeric binder can be prepared for sustained release, delayed sustained release, or delayed burst release. The sleep recovery active agent can be homogenously mixed or encapsulated within (coated) with the polymeric binder. For example, the sleep recovery active agent for sustained release can include a composition comprising the sleep recovery active agent and a sustained release polymeric binder homogenously mixed. In some examples, the sleep recovery active agent for delayed sustained release can include the sustained release active agent (i.e., the sleep recovery active agent and the sustained release polymeric binder) coated with a delayed release polymeric binder. In some examples, the sleep recovery active agent for delayed burst release can include the sleep recovery active agent coated with a delayed release polymeric binder. In specific examples, the delayed release polymeric binder can include a polymer selected from polyacrylate, methylcellulose, CARBOWAX™, or combinations thereof. The sleep recovery active agent can be in an amount of from about 0.5 wt % to about 55 wt %, based on the combined weight of the sleep recovery active agent and the polymeric binder. The polymeric binder can be in an amount of from about 0.5 wt % to about 99.9 wt %, such as from about 50 wt % to about 99.8 wt %, based on the combined weight of the sleep recovery active agent and the polymeric binder.

The next day active agent can include a composition comprising the next day active agent and optionally a polymeric binder. The next day active agent and the polymeric binder can be prepared for sustained release, delayed sustained release, or delayed burst release. In some examples, the next day active agent for sustained release can include a composition comprising the next day active agent and a sustained release polymeric binder homogenously mixed. In some examples, the next day active agent for delayed sustained release can include the sustained release active agent (i.e., the next day active agent and the sustained release polymeric binder) coated with a delayed release polymeric binder in some examples, the next day active agent for delayed burst release can include the next day active agent coated with a delayed release polymeric binder. The next day active agent can be in an amount of from about 0.5 wt % to about 55 wt %, based on the combined weight of the next day active agent and the polymeric binder. The next day active agent can be combined with the sleep recovery active agent, having the same release profile as the sleep recovery active agent.

In some examples, the composition containing the sleep promoting active agent, the sleep quality active agents, the sleep recovery active agent, and optionally the next day active agent can be formulated as a single unit composition. The single unit composition can be any suitable shape such as spherical, substantially spherical, flaked, rod shaped, square, oval, as well as any type of irregular shape. For example, the single unit composition can be rod-shaped bead, wherein the sleep promoting active agent can be located at the terminal ends of the bead, the sleep recovery active agent and optional next day active agent can be located in the middle of the bead, and the sleep quality active agent can be located between the terminal and central portions of the bead. In another example, the single unit composition can be a spherical bead (for example a multilayered particle) comprising the sleep promoting active agent on the surface, the sleep recovery active agent and optional next day active agent at the center, and the sleep quality active agent in between the sleep promoting active agent and sleep recovery active agent or throughout the bead. Thus, when the bead is ingested and digested, the timing of the release of the various active agents is in accordance with the timing of the bead's degradation in the gut or lower intestine. The active agent can be present in each layer for example, as a nanoparticle, a microparticle or a granule (including the active agent and a binder) or in its native form (that is, the active agent alone, not mixed with a binder). In some embodiments, the active agent (in the form of a nanoparticle, a microparticle, a granule, or its native form) can be combined with an additional material (such as a binder or bulking agent) to form a layer of the single unit or multi-unit composition.

In some examples, the sleep quality active agent, sleep recovery active agent, and optionally the next day active agent can be formulated as a single unit composition (for example a multilayered particle). For example, the single unit composition can be spherical bead, wherein the sleep recovery active agent and optional next day active agent can be located in the core of the bead, and the sleep quality active agent can be located as a first layer on the core's surface. Again, when the bead is ingested and digested, the timing of the release of the various active agents is in accordance with the timing of the bead's degradation in the gut or lower intestines. The sleep promoting active agent can then be administered as a separate composition along with the single unit composition containing the sleep quality active agent, the sleep recovery active agent, and the optional next day active agent. In some examples, the sleep promoting active agent along with the single unit composition can be dispersed in the comestible matrix and can be released by ingestion such as by chewing and/or swallowing or dissolution of the comestible matrix.

In some examples, the sleep promoting active agent, the sleep quality active agent, and optionally the next day active agent can be formulated as a single unit composition. In some examples, the sleep promoting active agent, optionally the sleep recovery active agent, and the next day active agent can be formulated as a single unit composition. The present disclosure is not limited by the particular combination of the sleep promoting active agent, sleep quality active agent, sleep recovery active agent, and/or the next day active agent.

In other examples, the sleep quality active agent, the sleep recovery active agent, and the next day active agent can each be formulated as separate beads (for example a single layered particle) For example, a spherical bead comprising the sleep quality active agent, a spherical bead comprising the sleep recovery active agent, and a spherical bead comprising the next day active agent can be administered together. The sleep quality active agent, sleep recovery active agent, or the next day active agent can be independently be located in the core or throughout the bead. One, two or all three of these beads can be coated with the sleep promoting active agent. Alternative, a separate sleep promoting bead can be used or the sleep promoting active agent can be part of a comestible matrix. An example of such a composition is disclosed in U.S. Pat. No. 8,545,892, which is incorporated by reference herein in its entirety for its teachings of beads for use in delivery of agents.

In some examples, the sleep promoting active agent, the sleep quality active agent, and the sleep recovery active agent, and optionally the next day active agent can be formulated as a single multilayered capsule. For example, the capsule can comprise a first layer comprising the sleep promoting active agent, a second layer (optionally disposed on the first layer) comprising the sleep quality active agent, a third layer (optionally disposed on the first or second layer) comprising the sleep recovery active agent, and optionally a fourth layer (optionally disposed on the second or third layer) comprising the next day active agent. When the bead is ingested and digested, the timing of the release of the various active agents is in accordance with the timing of the bead's degradation in the gut or lower intestines. Again, the active agent can be present in each layer for example, as a nanoparticle, a microparticle or a granule (including the active agent and a binder) or in its native form (that is, the active agent alone, not mixed with a binder). In some embodiments, the active agent (in the form of a nanoparticle, a microparticle, a granule, or its native form) can be combined with an additional material (such as a binder or bulking agent) to form a layer of the single unit or multi-unit composition.

The size of a single unit composition is not essential. The size of the single unit composition can be such that the composition can be seen in the comestible matrix without need for magnification, but also such that the composition is not substantially felt in the mouth or throat when being orally ingested. One suitable range for the diameter of the single unit composition is less than 5.0 mm, such as from 100 microns to 5.0 mm, from 300 microns to 5.0 mm, from 0.5 mm to 5.0 mm or from 0.5 mm to 2.5 mm. The single unit composition can also be much smaller, such as on a micrometer or nanometer scale.

The compositions (for example each single unit composition), can further include a coating layer to further change the rate of release of the active agent Additional coating layers will generally result in a delayed and/or slower release of the active agent. In some aspects, a thicker coating layer and/or crosslinked polymeric binders in the coating layer can result in a delayed and/or slower release of the active agent. In some aspects, the coating layer can be formulated such that external factors such as pH and osmosis can result in a delayed and/or sustained release of the active agent. In some examples, the coating layer can include a cellulose-based coating layer, such as an ethyl cellulose-based coating layer. The coating layer can be a SURELEASE™ coating layer as manufactured by Colorcon of West Point, Pa. The coating may be added in any amount to the compositions, for example, the coating can be added at less than about 15 wt % of the composition.

The compositions can also include additional components to alter the consistency, appearance, taste, smell, or shelf life of the beads or individual ingredients in the bead. These components may be added as either an additional ingredient in the beads, as a coating layer on an ingredient, or as a coating layer on the beads. In some examples, a coloring agent is used to alter the color of the beads. In some embodiments, a taste masking agent is used to alter the taste of the beads.

In some aspects, the composition can provide an immediate burst release of a sleep promoting active agent within about 30 minutes of administration. For example, the composition can provide an immediate burst release of the sleep promoting active agent from about 1 minute to about 30 minutes, about 1 minute to about 25 minutes, or about 1 minute to about 20 minutes after administration. In some examples, the composition can provide an immediate burst release of the sleep promoting active agent within about 30 minutes, about 25 minutes, about 20 minutes, about 15 minutes, about 10 minutes, about 9 minutes, about 8 minutes, about 7 minutes, about 6 minutes, about 5 minutes, about 4 minutes, about 3 minutes, about 2 minutes, or about 1 minute of administration. All or most (for example, 90% or greater) of the sleep promoting active agent may be released within this time. In some aspects, all or most of the sleep promoting active agent can be released within about 1 hour to about 3 hours. For example, all or most of the sleep promoting active agent may be released within about 1 hour, about 1.5 hour, about 2 hours, about 2.5 hours, or about 3 hours after administration.

In some aspects, the composition can also provide a burst release or sustained release of a sleep quality active agent within about 8 hours of administration. For example, the composition can provide a burst release or sustained release of the sleep quality active agent from about 10 minutes to about 8 hours, about 10 minutes to about 7 hours, about 10 minutes to about 6 hours, about 2 hours to about 6 hours, or about 2.5 hours to about 4.5 hours, after administration. In some embodiments, the composition can provide a burst release or sustained release of the sleep quality active agent within about 8 hours, about 7.5 hours, about 7 hours, about 6.5 hours, about 6 hours, about 5.5 hours, about 5 hours, or about 4.5 hours of administration. In some embodiments, the composition can provide a burst release or sustained release of the sleep quality active agent after about 1 hours, about 1.5 hours, about 2 hours, about 2.5 hours, about 3 hours, about 3.5 hours, about 4 hours, or about 4.5 hours of administration. Substantially all (for example, 90% or greater, 95% or greater, or 100%) of the sleep quality active agent may be released within this time.

In some aspects, the composition can further provide a delayed burst and/or delayed sustained release of a sleep recovery active agent after about 3 hours post administration. For example, the composition can provide a delayed burst or delayed sustained release of the sleep recovery active agent from about 3 hours to about 10 hours, about 3 hours to about 9 hours, about 3 hours to about 8 hours, about 4 hours to about 10 hours, about 4 hours to about 9 hours, about 4 hours to about 8 hours, about 5 hours to about 10 hours, about 6 hours to about 8.5 hours, or about 6.5 hours to about 8.5 hours, after administration. In some examples, the composition can provide a delayed burst or a delayed sustained release of the sleep recovery active agent after about 3 hours, about 3.5 hours, about 4 hours, about 4.5 hours, about 5 hours, about 5.5 hours, about 6 hours, or about 6.5 hours post administration. Substantially all (for example, 90% or greater, 95% or greater, or 100%) of the sleep recovery active agent may be released within this time.

In some aspects, the composition can further provide a sustained, delayed burst, or delayed sustained release of a next day active agent after about 3 hours post administration. For example, the composition can provide a delayed burst or delayed sustained release of the next day active agent from about 3 hours to about 10 hours, about 3 hours to about 9 hours, about 3 hours to about 8 hours, about 4 hours to about 10 hours, about 4 hours to about 9 hours, about 4 hours to about 8 hours, or about 5 hours to about 10 hours, after administration. In some examples, the composition can provide a delayed burst or a delayed sustained release of the next day active agent after about 3 hours, about 3.5 hours, about 4 hours, about 4.5 hours, about 5 hours, about 5.5 hours, about 6 hours, or about 6.5 hours post administration. Substantially all (for example, 90% or greater, 95% or greater, or 100%) of the next day active agent may be released within this time.

Methods of Making

The method of making the compositions disclosed herein is dependent on the desired rate of release of the active agent. The rate at which the active agent is released, for example under physiological conditions or in the stomach or the lower intestines can be controlled by the type and amount of binder used in the composition. A composition with relatively minor amounts of binding agents will be broken down quickly in the digestive tract, while compositions with higher amounts of binding agents and coatings will break down relatively slowly.

Methods of making a single unit composition comprising an active agent encapsulated in a binder is describe in U.S. Pat. No. 8,545,892, the disclosure of which is incorporated herein by reference. In short, the method can include blending the active agent, the binder, and a suitable solvent to form a mixture. The mixture can then be extruded and optionally unitized to form a single unit composition.

A multi-layered single unit composition can be prepared by first creating the core layer. The core layer can be prepared as described above. A first layer can be deposited on the outer surface of the core layer by mixing the core particle with a solution or suspension of the ingredients in the first layer. After deposition of the first layer on the core particle, the single unit dosage composition can be collected by centrifugation followed by washing. A second layer can be deposited on the outer surface of the first layer similar to deposition of the first layer.

The single unit composition can be dispersed in a comestible matrix by mixing the single unit dosage composition with any suitable comestible phase. For example, the single unit composition can be mixed with a chocolate base.

The composition comprising the single unit composition and the comestible matrix can be formulated as a daily oral single dosage form

Methods of Using

Methods of treating a sleep disorder or a subject having an abnormal sleep-wake cycle in a subject are also disclosed. Sleep disorder, as used herein includes, but is not limited to, insomnia, difficulty falling asleep, difficulty staying asleep, narcolepsy and its clinical manifestations such as sleep attacks, cataplexy, sleep paralysis, hypnagogic hallucinations, sleep apnea, hypersomnia, failure to wake-up feeling refreshed and rested or fatigue on waking, and related disorders. In some examples, the sleep disorder comprises fragmented sleep architecture.

In some aspects, treating a sleep disorder or modifying or improving the sleep-wake cycle in a subject includes improving sleep sensation determined by subjective judgment using psychological evaluation techniques or improving the sleep state determined objectively using techniques of estimating sleep and wakefulness states based on continuous recording of activity amounts. For example, the obstructive sleep apnea questionnaire can be used to examine the sleep sensation of the previous night to the present morning upon arising. The questionnaire is based on the five factors of sleepiness upon arising, sleep initiation and sleep maintenance, dream quality, recovery from fatigue, and elongation of sleep length and has been verified in regard to the reliability and validity of the respective factors.

Methods of sleep recovery including enhancing mental acuity or cognitive activity in a subject are also disclosed. Specifically, methods of sleep recovery after sleeping without unpleasant feeling or grogginess are disclosed. Sleep recovery can be determined objectively by measuring changes in the brain activity within the alpha frequency band using an electroencephalogram, or subjectively using the Toronto Hospital Alertness Test (THAT).

The method can include administering a sleep promoting active agent that provides a burst release of the sleep promoting active agent within about 30 minutes of administration, administering a sleep quality active agent in the form for a burst and/or sustained supply of the sleep quality active agent within about 6 hours of administration, administering a sleep recovery active agent after about 3 hours of administration of the sleep promoting active agent, and optionally administering a next day active agent in the form for a sustained, delayed burst, and/or delayed sustained supply of the next day active agent upon administration.

The method can include administering one or more sleep quality active agents that upon administration provides a delayed burst or delayed sustained release of the sleep quality active agents within about 6 hours of administration, and optionally administering one or more sleep recovery active agents that upon administration provides a delayed burst or delayed sustained release of the sleep recovery active agents after about 3 hours of administration, and administering one or more next day active agent that upon administration provides a delayed burst or delayed sustained release of the next day active agent after about 3 hours of administration. The method can include administering one or more sleep recovery active agents that upon administration provides a delayed burst or delayed sustained release of the sleep recovery active agents after about 3 hours of administration, and administering one or more next day active agent that upon administration provides a delayed burst or delayed sustained release of the next day active agent after about 3 hours of administration.

In some aspects, the methods of treating a subject with a sleep disorder or modifying or improving the sleep-wake cycle in a subject can include administering any one of the compositions described herein. In some aspects, the methods of treating a subject or modifying or improving the sleep-wake cycle in a subject with a sleep disorder can include administering two or more of the compositions described herein. The active agents can be administered simultaneously, for example in the form of a single unit composition or separately.

This composition is not limited in particular in terms of administration method, number of times of administration, administration period, etc., and can be administered once or in a plurality of times by a suitable form of administration. In some embodiments, the composition is administered orally, once daily.

In some examples, the sleep disorder is a dyssomnia. Dyssomnia can include psychophysiological insomnia, sleep state misperception, idiopathic insomnia, obstructive sleep apnea syndrome, central sleep apnea syndrome, central alveolar hypoventilation syndrome, periodic limb movement disorder, restless leg syndrome, inadequate sleep hygiene, environmental sleep disorder, altitude insomnia, adjustment sleep disorder, insufficient sleep syndrome, limit-setting sleep disorder, sleep-onset association disorder, nocturnal eating or drinking syndrome, hypnotic dependent sleep disorder, stimulant-dependent sleep disorder, alcohol-dependent sleep disorder, toxin-induced sleep disorder, time zone change (jet lag) syndrome, shift work sleep disorder, irregular sleep-wake pattern, delayed sleep phase syndrome, advanced sleep phase syndrome and non-24-hour sleep-wake disorder.

Example 1: Preparation of Soft Chew Composition

Capsules were prepared as detailed in Table 1 and as described below. Powders from each of the following active ingredient were prepared by mixing with a polymeric binder for 3 minutes in a low shear planetary mixer:

-   -   Valerian root extract     -   PHARMAGABA™     -   5-HTP (5-Hydroxytryptophan)     -   Melatonin, and     -   SUNTHEANINE™         Water was then added to the powder mixture to produce a wet         mass. The wet mass was passed through an extruder at 50 rpm. The         extrudate was spheronized in a spheronizer at 1000 rpm for 1         minute to produce spherical beads. The spherical beads were         dried until the moisture content was reduced to less than 5 wt         %.

Compositions comprising RELORA™ and Valerian root extract were prepared as describe above, except a taste masking agent was used instead of a polymeric binder.

A sustained release capsule was prepared by mixing the beads prepared from the valerian root extract, PHARMAGABA™, 5-hydroxytryptophan, melatonin, SUNTHEANINE™, and RELORA™, as well as 5-hydroxytryptophan, magnesium glycinate, PHARMAGABA™, riboflavin 5′-phosphate sodium, pyridoxal-5-phosphate monohydrate, melatonin, (6S)-5-methyltetrahydrofolic acid, glucosamine salt, methylcobalamin with a comestible matrix.
